ANDEIE, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR TO 'W'. B. JARVIS GOM- PANY, 0F GRAND RAPlDs, MICHIGAN onosnnnron RADIATOR nnons AND THE LIKE:

Application filed A rnia The main objects'iof this invention are:

First, to provide a closure for radiator necks, oil tanks and the like, which may be very quickly applied or removed, the neck or opening being very efiectively sealed.

Second, to provide a closure having these advantages in which the parts are very simple and economical in structure and easily assembled, and at the same time are very strong anddurable.

Objects pertaining to details and economies of my invention will definitely appear from the description to follow. The invention is defined in the claims.

A structure which embodies the features of my invention is clearly illustrated in the accompanying drawingin which:

l is a vertical central section through a radiator closure embodying the features of my invention.

Fig. 2 is a fragmentary plan View of the neck partially in section on a line corresponding to line 2-2 of Fig. 1.

,Fig. 3 is an inverted view of the cap with the closure disk and gasket or packing disk omitted.

Fig. & is a fragmentary section on line 4-4 of Fig. 3. a

In the accompanying drawing the embodiment illustrated is such as I employ for radiator openings and the like. It will be understood that my improvements have very wide adaptability but it is believed that this disclosure will enable such adaptation as may be desired. V v

The neck 1 is provided with an out-turned flange 2 providing an annular gasketv seat. On the outer edge of this flange I form two ormore segmental downwardly converging or downwardly tapered male, joint or coupling members 3. These coupling members 3 are in the form of a flange-like projection on the outer edge of the flange 2 and are provided with stops 4 at corresponding ends thereof.

The cap 5 is provided with a downwardly projecting flange-like rim 6 and with a central dependingshank 7 shouldered at 8. The rim or flange of thecap is provided with segmental inwardly projecting downwardly 192a. Serial No, 355,105.

8 of the shank,'the disk-like gasket'12 be-,

ing arranged on the under side thereof and clamped thereon. by means of the clamping disk-l3 retained by means of the screw 14. threaded into the shank. The gasket disk is preferably of the same diameter as the closure disk and is clampeduponthegasket seat of the neck by means of the spring closure disk.

The disk is provided with anannular beadlike rib' 15 opposed to an annular bead-like rib 16 formed in the neck gasket seat. This insures a sealing joint for the neck.

.The parts are simple in structure, easily assembled and'the cap may be quickly applied or, removed. My improvements are well adapted for-closures for radiators; and

the like, the cap lying close to the neck.

Having thus described my invention what is provided with.

I claim as new and desire to secure by Letters Patent is: j Y t 1. In a closure, the combination of aneck having an out-turned annular flange provided with opposed segmental'downwardly converging coupling members depending from its edge, saidcoupling membershaving stops at corresponding endsjthereof, a cap having a shouldered central depending shank and a. dependingrim, said rim havingisegmental. downwardly converging coupling members engageable and disengageable with said couplingmembers-of said neck by a rotative movement, a spring-closure disk seated on said shoulder ofsaid shank with its outer edge in overhanging relationto said flange on said neck, said disk-and fia n'ge having opposed annular beads, a disk-dike gasket a1' 1y inclined male jointmembers, a cap proranged on said shank below said closure disk, and a gasket retaining disk mounted on the inner end of said shank in overlapping relation to the under side of said gasket.

2. In a closure, the combination of a neck having an out-turned annular flange provided with opposed segmental converging coupling members depending from its edge, said coupling members having stops at corresponding ends thereof, a cap having a central depending integral shank and a depending rim, said rim having segmental downwardly converging coupling members engageable and disengageable with said coupling mem bers of said neck by a rotative movement, a spring closure disk seated on said shank with its outer edge in overhanging coacting relation to said flange on said neck, said disk and flange having opposed annular beads, and a gasket disposed therebetween.

3. In a closure, the combination of a neck having an out-turned annular flange provided with opposed segmental converging coupling members depending from its edge, a cap having a depending rim provided with segmental downwardly converging coupling members engageable and disengageable with said coupling members of said neck by a rotative movement, a spring disk mounted within said cap in coacting relation to said neck, said disk and flange having opposed annular beads, and a gasket disposed therebetween.

4. In a closure, the combination ofa neck having an annular outwardly projecting flange provided with opposed segmental downwardly converging joint members depending from its edge, said joint members having stops at corresponding ends, a cap having a central depending integral shank provided with opposed segmental clownwardly converging joint members engage able and disengageable with said joint members of said neck by a rotative'movement, a disk-like spring closure member seated on said shank with its outer edge'overhanging said neck, and agasket member supported below said disk to coact with said neck, said flange and closure member being provided with opposed annular ribs.

5. In a closure, the combination of a sheet metal neck provided with segmental downwardly converging joint members, a cap provlded with coacting segmental downwardly converging joint members engageable and closure member arrangedwithin said cap in opposed relation to said neck and acting to apply spring tension tosaid joint members when they are inen'gagemenfland a gasket carried by said cap.

6. In a closure, the combmation of a sheet metalneckprovided with segmental inwardwardly tapered male joint members, a cap provided with coacting downwardly tapered socket joint members engageable and disengageable with said male joint members by a relative rotative movement, and a spring closure member carried by said cap and provided with a gasket coacting with the neck to close the neck and apply spring tension to the joint members.

. 8. In a closure, the combination of a sheet metal neck provided with segmental downwardly tapered coupling members, a cap provided with coacting segmental downwardly tapered joint members engageable and disengageable with said joint members of said neck by a rotative movement, and a spring thrust closure member arranged within said cap in opposed relation to said neck and acting to apply spring tension to saidjoint members when they are in engagement. I

' 9. In a closure, the combination of a sheet metal 'neck provided with segmental downwardly tapered male joint members, a cap provided with coacting tapered socket joint members engageable and disengageable with said male joint members by a relative rotative movement, and a spring closure member carried by said cap and acting to apply spring tension to the joint members when they are in engagement.

10. A sheet metal neckha-ving an annular flange provided with depending inwardly tapered resilient projections, a cap therefor having a central integral shank, a sheet metal disk secured to said shank, and a asket secured to said disk for engaging said ange, said cap having an integral skirt embracing said neck in spaced relation, and said skirt havingtapered integral lugs adapted to register with said projections.

In witness whereof I'have hereunto set my hand.
